Owen's three biggest loves are eating, having a good time, and passing a large amount of gas. Among his peers, he is arguably the most popular contestant of all time for his cheerful ways, optimistic viewpoints no matter what the situation, and ability to see the best in people. He even accomplishes the impossible in making a friend of Chris. He always tries to help his team win challenges despite his physical and mental disadvantages. Usually enthusiastic at first, he often ends up failing, the majority in humorous ways. As a running gag in the series, Owen is frequently naked, farting, or sometimes both. He has mentioned on numerous occasions that his response to stress (among many other emotions) is eating. Owen is also a sensitive person, describing himself as feeling things on a deep level. Despite being one of the nicest contestants on the show, Owen has a dark side like most others.

Owen appears in the special episode along with the rest of the contestants, mostly interacting with Scott. He is then introduced by Chris as one of the four new contestants to be joining the fourth season, and is very excited by this, so he hugs Noah, Scott, and Alejandro. While on the plane, Alejandro gets extremely annoyed with Owen, as he calls him "Al" and not his full name, Alejandro. Owen then officially becomes a competitor in Total Drama Toxic Brawl, and is seen with the other contestants in the air by a bomb.

When Owen arrived at the island his mouth was shut because he had a stomach ache. He was placed on team Toxic Sharks and then fainted so he didn't help the team a lot. In the end the Sharks won and Brick was added to Owen's team and they celebrated victory.

Owen was happy that he and his team won the first challenge and said that he liked Eva, but she just got annoyed. He was a little helpful to the team and like always, he was hungry. He liked the paintball gun he received and then did okay in the challenge.
